To all whom it may concern.-

Be it known that I, HIRAM M. THOMPSON, a cltizen of the United States,residing at Logan, 1n the county of Gallatin and State of Montana, haveinvented certain new and useful Improvements in Hay-Stackers and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which 1tappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked plhereon,which form a part of this specifica ion.

My invention relates to hay-stackers, and has for its object to providea device of this class which will stack hay with a minimum amount ofpower and in the shortest possible period of time.

A further object of my invention is to provide a hay-stacker which issimple in its construction, cheap and easy to manufacture, strong,durable, and efficient.

With these objects in view my invention consists in the novelconstruction of the triangular operating-frame.

My invention also consists in certain other novel features ofconstruction and in combinations of parts, which will be first fullydescribed and afterward specifically pointed out in the appended claims.

Referring to the accompanying drawings, Figure 1 is a perspective viewof the hay stacker in a lowered position. Fig. 2 is an elevation of thehay-stacker in a partlyraised position; and Fig. 3 is an elevation ofthe hay-stacker in its highest position, parts being broken away inorder to enlarge the view.

Like numerals of reference indicate the same parts throughout theseveral figures, in which- 1 indicates the stacker, which comprises thelongitudinal frames 2, the transverse base-pieces 3, the verticaluprights 4, the horizontal frame-pieces 5, the transverse braces 6, andthe longitudinal braces 7.

Connecting the central vertical uprights 4 is a transverse horizontalbrace 8, supported by two braces 9, and connecting the rear uprights 4is the transverse horizontal brace supported by braces 11.

Secured to the horizontal frame-pieces 5 on the inside thereof is acurved rack-plate 12, said rack-plate being inclined, as shown, andsecured also to the longitudinal brace 13. Supported by the centraltransverse brace 8 and the rear transverse brace 10 are two curvedrack-plates 14.

Pivoted between the front vertical upright 4 and a short post are thelong movable arms 16. Secured to the rear ends of said arms are twotransverse pieces 17, and stiffening said arms is a brace 18. Secured tothe under side of the transverse pieces 17 are the hay-stacking fingers19, and secured to the said movable arm 16 and also to the saidhaystacking fingers 19 are the hay-supporting fingers 20, said latterfingers being also secured to the transverse piece 21 and to alongitudinal brace 22, as clearly shown in Figs. 1 and 2.

23 indicates the non-pivoted traveling triangular operating frame orlever, which comprises the forward piece 24, the short side 25, and therear piece 26, said parts being secured together to form a triangle, asclearly shown. Connecting the pieces 24 is a transverse horizontal brace27, and also connecting the said pieces 24 is a transverse horizontalbrace 28, Figs. 2 and 3.

Connecting the sides 25 and 26 is the transverse horizontal frame 29,and secured to the sides 25 and supported by the frame 29 are the twoframe-pieces 30, which are connected together at their rear ends, andconnecting the sides26 with the transverse horizontal frame-piece 29 arethe bracing-pieces 31.

Secured to the transverse horizontal framepiece 28, Fig. 2, is ametallic yoke 32, and located in said yoke, as shown, is a roller 33.Connecting the said yoke with the rear ends of the frame-pieces 30 is arod 34, the movable arm 16 passing through the yoke 32 and resting onthe rollers 33 therein.

The pieces 24 and 25 of the triangular operating frame or lever 23 areprovided with racks 35 and 36, and the points formed by the two sides 24and 25 are provided with a metallic strip or plate 37. A small metallicstrip or plate 38 is provided in the angle formed by the rack-plates 12and the longitudinal braces 13, to which said rack-plates are secured.

39 indicates the operating-cable, which is connected to the frame-pieces30 at the point 40, said cable 39 passing forward and around the pulley41, whence it is again carried. back and around the pulley 42, locatedon the frame 30. The cable is again carried forward under the pulley 43,where it passes to a suitable Windlass or where it can be grasped byhand to be pulled manually.

Located on the horizontal brace-pieces 5 are two uprightoutwardly-curved guides 44.

Having thus fully described the several parts of my invention, itsoperation is as follows: Referring to Fig. 1, which shows the device inperspective and which illustrates the non-pivoted, revoluble, and movingtriangular operating frame or lever 23 in an inverted vertical position,the hay-stacking fin.- gers 19 being in a horizontal position and thehay-supporting fingers 20 in a substantially vertical position, it willbe seen that the said triangular operating frame or lever 23 issupported on the curved rack-plate 1 1. As the end of the cable 39 ispulled by any suitable power, the triangular operating frame or lever 23is turned forward until it reaches the position shown in Fig. 2, therack 35 on the said operating frame or lever 23 acting on the curvedrack-plates 14, thus bringing the said triangular operating frame orlever 23 for- Ward and causing the points 37 thereof to engage the angle38 between the curved rackplate 12 and the longitudinal brace 13, asshown in Fig. 2. A further pull on the cable 39 causes the rack 36 ofthe operating frame or lever 23 to engage the curved rack-plate 12, andas the cable 39 is pulled the said operating frame or lever 23 movesforward on the said curved rack-plate 12 until it reaches the positionas shown in Fig. 3, which illustrates the triangular operating frame orlever 23 in an upright position. As the yoke 32, which is carried bytheoperating frame or lever 23, is in engagement with the movable arm16, carrying the hay-stacking teeth 19 and 20, said arm 1.6 andhay-stacking teeth are carried from a horizontal to a vertical positionby the movement of the operating frame or lever 23, as is illustrated inthe three positions shown in Figs. 1, 2, and 3. A quantity of hay havingbeen pitched upon the haystacker and fingers 19, when the said fingersare in position shown in Fig. 1, the said hay is raised and stacked whenthe arms 16 are raised in a vertical position by the movement of theoperating frame or lever 23, as is obvi ous. Thus it is seen that haycan be quickly and effectually stacked by this device in a very shortperiod of time and in an easy and convenient manner. As the operatingframe or triangle 23 is passing from the position shown in Fig. 1 tothat shown in Fig. 2 the small guide-pieces 1 1, located on thehorizontal frame-pieces 5, guide the said triangular frame so as toinsure a proper movement of the same and to prevent the said triangularframe or lever from striking the horizontal frame-pieces 5 during therotation of the said triangular frame.

I-Iavingthus fully described my invention, f d'o not wish to beunderstood as limiting myself to the exact construction as herein setforth, as various slight changes may be made therein which would fallwithin the limit and scope of my invention, and I consider myselfclearly entitled to all such changes and modifications.
